PASSAGE-WAY FOR BULKHEADS AND PARTITIONS.

SPECIFICATION forming part of Letters Patent No. 608,189, dated August2, 1898.

Application filed September 22, 1897, Serial No.'652,527. (No model.)

To Utah/0m it may concern:

Be it known that l, DALLAS DU 1301s, of Montclair, in the county ofEssex and State of New Jersey, have invented a new and In1- provedPassage-WVay for Bulkheads and Fartitions, of which the followingis afull, clear, and exact description.

The object of the invention is to provide a device whereby commnnication may. be obtained between one compartment and another and yeta water and fire proof division be maintained between said compartments.

Another object of the invention is to provide a means wherebywhen thedoor in one compartmentis openedthe door in the other compartment willbe closed and whereby the doors in both compartments may be closed orsealed when desired, and also to provide a means whereby a single personmay operate the device conveniently and expeditiously.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthisspecification in which similar characters of reference in dicatecorresponding parts in all the figures.

verse section taken substantially on the line 4: 4. of Fig. 2. v

A may represent either the hull of a vessel or the wall of a building,and B the top, and B the bottom; of one or more compartments therein.Two partitions 10 and 11 are carried from side to side of the structureA, a space intervening the two partitions. The partitions are shown asdividing the structure into two compartments 0 and C. It is the purposeof the invention to provide a water-tight and fireproof connectionbetween the two compartments 0 and O. This is accomplished by locatingin the space between the partitions acar D. The partition 10 is providedwith a doorway 10?, and the partition 11 is provided with a doorway 11,the two doorways 1O and 11 being out of transverse alinement, as shownin Fig. 1. The car D is preferably made without a top, and especiallywithout a bottom, and is free to travel in the space between the twopartitions. Ordinarily'the car D is supported by hangers 16, carryingsuitable rollers or wheels, which rollers or wheels travel on tracks 17,attached to the opposing faces of the aforesaid partitions 10 and 11.The car is provided at its center with oppositely-located doorways 13and 14.

Upon the inner face of one side of the car a lock-lever 18 is fulcrumed,the latch end of the lever being preferably curved above the car, andupon the corresponding surface of the opposing face of the car a likelever 19 is pivoted, the two levers facing in opposite directions, asshown in Figs. 1 .and 2. Two shafts 20 and 21 are transversely mountedin the car, the shafts being of such length as to extend through andbeyond horizontal slots or openings 22, made in the partitions 101 and11, as illustrated in Figs. 1 and 3. Each of the shafts 20 and 21 ispreferably provided with a T-handle 23 at its outer end, and the shaftsare held in predetermined position by springs 24 at their ends, asillustrated in 27, extending in opposite direction to the crank-arm 25,the crank-arm being connected by a link 28 with the lock or latch lever19, as shown in dotted lines in Fig. 1.

Two pins 30 and 31 are located upon the inner face of the partition 11,near one end thereof, and corresponding pins 32 and 33 are projectedfrom the opposing partition 10 at the opposite end, so that the two setsof pins 30 and 31 and 32 and 33 are diagonally opposite. These pins areadapted for engagement by the latch-heads of thelock levers, and whenthe said lock-levers are in engagement with the end pins the car will beso held that one of the doorways therein will register with one of thedoor-openings in the partitions, the doorway in the opposite partitionbeing closed. When a lock-lever, however, is-in engagement with one ofthe inner pins-the inner pin 31, for examplethe car will be locked insuch position that all communication will be cut off from thecompartment 0 to the compartment 0; but

- it will be understood that by turning either the shaft 20 or 21, withwhich the lock-latch may be connected, and moving the shafts along theslots'22 the car may be moved between the partitions, and one of itsdooropenings may bemade to register with an opening in either thepartition 10 or the partition 11, so that a person in the compartmenthaving communication with the car may enter said car. The car is thenmoved by the operator grasping handles 15, for example, attached to thecar, until the opposite door-opening in the car is brought in registrywith the door-opening in the opposite partition, whereupon the person inthe car may step out into the opposing compartment 0.

It is evident that this device is equally applicable to the partitionsin buildings as to the bulkheads in ships and like structures and that apacking may be provided between the car and the patitions, between whichit moves, which will render the communication between the compartmentseither fireproof or water-tight. In the event a person is within the.car and the lock-latch is in looking connection with a pin or stud onthe partition disengagement between the lock-latch and said pin or studmay be readily effected by drawing down on the cord, rope, or chain 29.

I desire it to be understood that if the device is to be used on landthe lock-latches need not be employed, the lock-latches being especiallydesigned to hold the car in required position upon the vessel when thevessel is affected by the motion of the water. The

shafts 20 and 21 are shown as extending across the car. These shafts,however, may be and preferably are made to extend through but onepartition and one side of a car. The device is intended to be workedfrom the inside almost exclusively, being worked from the outside onlywhen both door-openings in the car are out of registry with thedooropenings in the partition.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, with opposing partitions providedwith openings out of registry with each other, of a car mounted totravel between the partitions and provided with opposing openings, forthe purpose set forth.

2. The combination, with partitions having a space between them, thepartitions being provided with openings out of transverse registry, of acar mounted to travel in the space between the partitions, the carhaving opposite openings, and means for shifting the car, substantiallyas described.

3. The combination, with opposing partitions having openings in oppositesides diagonally arranged in relation to each other, of a car mounted totravel between the partitions, the car being provided with opposingopenings, means, substantially as described, for operating the car, anda locking device for the car, substantially as described.

4. The combination, with opposing partitions, each having an opening,the openings in the partitions being in diagonal arrangement withrelation to each other, of a car held to travel between the partitions,locklatches pivoted to the said car, facing in opposite directions,spring-controlled shafts arranged to raise or lower the saidlock-latches, and keepers carried by the partitions, adapted forengagement with the said lock-latches, for the purpose specified.

5. The combination, with opposing partitions having openings therein,the openings in the partitions being in diagonal arrangement in relationto each other and the said partitions being provided with longitudinalslots, of a car held to travel between the partitions, said car beingprovided with oppositely-located openings, shafts carried by the saidcar and extending outward through the openings in the partitions,lock-latches located at opposite sides of the car, facing in oppositedirections, crank arms projected from the shafts, and link connectionsbetween the crank-arms and the lock-latches, and keepers located uponthe partitions, arranged for engagement with the lock-latches, thekeepers being upon the inner faces of the partitions and located atdiagonally opposite ends, as and for the purpose specified.
